How do you get a dead critter out of the vent pipe that goes to the hot water heater as is dripping yuck on the hot water heater and stinks?

To remove a dead critter from the vent pipe of your hot water heater, first, ensure the heater is turned off for safety. Use a flashlight to locate the critter, then carefully use a pair of long tongs or a grabber tool to extract it. If the critter is not easily accessible, consider using a vacuum with a hose attachment to suction it out. Finally, clean the area thoroughly to eliminate any odors and prevent further issues.
